Shaky camera work for the 1964 NME show.

I'm watching this right now and was wondering why some of the camera close ups have these weird shaking movements. It's almost as if the camera operators were stamping their feet to the music while filming. This in the pre psychedelic drugs days. I'm wondering if this was intentional or accidental. (some of those drugged up camera operators ruined some great performances)

 

I’m guessing the audience around the camera operators were stamping their feet causing the cameras to shake.

 

When I saw The Beatles at Shea Stadium in 1966 the stadium shook which made me nervous. When John Lennon made his last live performance at an Elton John concert, Madison Square Garden shook so much I had trouble standing much less trying to take a photo.
